ChatGPTQuick Summary
- Only 23% of 181 surveyed sellers ($2B+ combined revenue) are classified as "thriving" with growing revenue and healthy margins
- Four cohorts identified: thriving (23%), grinding (38%), consolidating (24%), and distressed (15%), each facing different strategic realities
- The index reveals that platform-level GMV growth masks deep profitability divergence at the seller level
- Sellers in the "grinding" cohort (largest group) show revenue growth but declining margins, often due to rising ad costs and fee stacking

What the Data Shows
Marketplace Pulse surveyed 181 Amazon and e-commerce sellers representing over $2 billion in combined annual revenue. The results paint a picture that contradicts the headline numbers. While Amazon's GMV hit record highs in 2025, seller-level profitability tells a different story. Only 23% of respondents qualify as "thriving," with growing revenue and healthy margins. The rest are spread across three progressively harder cohorts. Across the agency portfolios we monitor, this kind of change usually surfaces in custom views built around fee deltas, not in the standard reports.
This is the first comprehensive seller sentiment index of 2026. It matters because platform-level growth numbers mask what's actually happening at the individual seller level. You can't benchmark your business against Amazon's $830B GMV. You need to know where you stand relative to sellers in your revenue bracket.

The Four Seller Cohorts
Thriving (23%)
Revenue growing and margins healthy or improving. These sellers share common traits: diversified product lines (average 50+ SKUs), strong brand presence with A+ Content, and disciplined ad spend with TACoS under 12%.
Most thriving sellers actively manage their unit economics at the SKU level, not just aggregate P&L. They cut losers fast and double down on winners.
Grinding (38%)
The largest cohort. Revenue is growing, but margins are declining. This is the most dangerous position because it feels like progress. You're selling more, but keeping less.
The primary margin killers: rising ad costs (average CPC up 18% YoY), fee stacking from inbound placement and low inventory fees, and competitive pricing pressure forcing lower ASPs. Grinding sellers often lack visibility into which SKUs are actually profitable.
Consolidating (24%)
Revenue flat or slightly declining, but margins stabilizing. These sellers are strategically shrinking. They're cutting unprofitable SKUs, exiting categories with unsustainable ad costs, and focusing on their core winners.
Consolidation isn't failure. It's a rational response to a marketplace where being big doesn't mean being profitable. Many consolidating sellers report higher net profit despite lower revenue.
Distressed (15%)
Revenue declining and margins compressed or negative. These sellers face existential questions: exit the marketplace, pivot to wholesale, or attempt a turnaround.
Common patterns in distressed sellers: over-reliance on a single product or category, TACoS above 25%, and inability to adapt to fee increases. Many are running on cash reserves without a clear path back to profitability.

What This Means for Your Business
- 1.
Identify Your Cohort
Be honest about where you stand. Revenue growth without margin health puts you in "grinding" territory, not "thriving." Check your trailing 6-month trend on both metrics before planning your next quarter.
- 2.
Track Unit Economics at SKU Level
The biggest difference between thriving and grinding sellers is visibility. Thriving sellers know exactly which products make money after all fees, ads, and returns. Use Nova's P&L Dashboard to get SKU-level profitability in real time.
- 3.
Cut Losers Before Scaling Winners
Consolidating sellers who pruned unprofitable SKUs reported higher net profit despite lower revenue. Don't scale until you've eliminated margin drains. Losing products consume ad budget, warehouse space, and management attention.
- 4.
Control Your Ad Spend Ratio
TACoS is the clearest dividing line between cohorts. Track it weekly using PPC Management tools and set hard ceilings per product. If a SKU's TACoS exceeds 15%, it needs a strategic review.
